Synthetic gauge fields in quantum gases of dysprosium
ORAL
Abstract
To the toolbox of quantum gas-based many-body physics, highly magnetic atoms offer large, possibly non-perturbative, long-range dipolar interactions concomitant with extraordinarily large SU(2) spinors and novel atomic structure. We report on our recent proposal [1] to create a diversity of exotic quantum many-body phases--non-Abelian quantum magnets, high-spin quantum Hall states--using the unusual properties of dysprosium under the influence of large light-induced gauge fields, both Abelian and non-Abelian, to generate large synthetic magnetic fields and spin-orbit coupling. We will describe recent experimental progress as well as new results on the collisional properties of quantum dipolar Bose and Fermi gases of Dy, recently produced in our laboratory for the first time [2,3], including Feshbach resonance spectra [4]. \\[4pt] [1] X.
